OBJECTIVE To evaluate the Doppler sonographic findings of the left renal vein in children with orthostatic proteinuria in comparison with healthy children and to propose more reliable sonographic criteria for diagnosing nutcracker syndrome in children. METHODS Doppler sonographic findings in 47 children with orthostatic proteinuria and in 27 healthy(More)
OBJECTIVE We prospectively evaluated transabdominal and transvaginal sonographic findings of patients with pelvic congestion syndrome and compared them with those of healthy volunteers. SUBJECTS AND METHODS. We examined 32 patients with pelvic congestion syndrome and 35 control subjects. Using transabdominal sonography, we evaluated the ovarian veins for(More)
OBJECTIVE We describe the sonographic findings of nasal fracture in children, and we evaluate the diagnostic value of sonography as compared with conventional radiography and clinical findings to determine whether sonography can be a primary technique for evaluating nasal fracture in children. MATERIALS AND METHODS Conventional radiographs and sonographic(More)
Purpose: To compare follow-up results of sclerotherapy for renal cyst using 50% acetic acid with those using 99% ethanol as sclerosing agents. Methods: Eighty-one patients underwent sclerotherapy and 58 patients, 23 males, 35 females, aged 6–76 years, having a total of 60 cysts, were included in this study; the others were lost to follow-up. The renal cysts(More)
Hepatocellular carcinoma (HCC) has a tendency to rupture spontaneously which leads to a life-threatening condition. Disruption of the tumor surface or a tear in a parasitic feeding artery can cause HCC rupture leading to hemoperitoneum. When evaluating patients with a ruptured HCC, CT can detect tumors, determine tumor extent, define the presence of tumor(More)
OBJECTIVES The purpose of this study was to retrospectively evaluate the sonographic findings compared with magnetic resonance (MR) arthrographic and arthroscopic findings in diagnosis of anterosuperior labral tears of the hip. METHODS The Ethics Committees of our institution did not require patient approval or informed consent for this retrospective(More)
OBJECTIVE To evaluate the prevalence of known risk factors for contrast-induced nephropathy (CIN) and their association with the actual occurrence of CIN in patients undergoing intravenous contrast-enhanced computed tomography (CECT) in Korea. MATERIALS AND METHODS Patients who underwent CECT in 2008 were identified in the electronic medical records of 16(More)
Abdominal CTs of 57 patients with bowel perforation after blunt abdominal trauma were retrospectively analyzed to determine: the diagnostic accuracy of the perforation site, and the differential findings according to the elapsed time from the trauma. Diagnostic accuracy of the perforation site was as follows: duodenum (100%), jejunum (81%), jejunoileal(More)
Choledochal cysts are rare congenital anomalies which are principally diagnosed by disproportional dilatation of the extrahepatic bile ducts. In addition, choledochal cysts are believed to arise from the anomalous union of the common bile duct and pancreatic duct outside the duodenal wall which is also proximal to the sphincter of the Oddi mechanism. The(More)
Computed tomography (CT) is an accurate and effective modality for the diagnosis and staging of appendicitis. CT provides rapid and complete evaluation of patients with suspected appendicitis and clearly demonstrates the typical findings of appendicitis, including a distended appendix, periappendiceal fat stranding, an appendicolith, and focal thickening of(More)
